Right Ive been doing some testing and have realised that my team has two huge weaknesse, rock and water! So ive decided to replace on of my pokemon with a good grass type. I have only two in mind
Ludicolo
Pros
-solid typing
-can counter rain well
-good movepool
Cons
-gives my team a new weakness in flying
-doesnt learn spikes (would be very helpfull)
Ferrothorn
Pros
-can learn spikes
-good against fairys
-has staying power with leech seed+iron barbs
Cons
-X4 fire weakness
-its widely used so has a lot of pokemon that deal with it well
And thats it i'm having a hard time choosing so any help is appriciated
Thanks
Both options are solid, especially Ludicolo if you bring rain; otherwise, stick with Ferrothorn.
However, you should try, if you have not used it, Rotom-Grass. Its typing is superior and learns both Volt-Turn and the Draco-Meteor-grass equivalent.
Tbh it might help if you posted the rest of your team so we can see what you already have/what you need from this grass type.
If you happen to wield TR, the pumpkin would be useful. But that's unlikely. So, let's see the team.
